<<Disclaimer: Verify this information before applying it to your situation.>> Sorry to have missed the original request for info on food additive books, but I just bought the following book and find it very well written, indexed, referenced, and detailed. "Food and food additive intolerance in childhood" By T.J David. Blackwell Scientific Publishers (1993) ISBN 0-632-03487-4. The book is divided into 18 parts, including major sections on cow's milk intolerance, soya, egg, cereal, food additives. Anything you can think of, and probably many you haven't thought of are to be found (did you know, for instance, that farmed salmon may have a pigment (canthaxanthin) added to their diet to colour the flesh so that it resembles that of "wild" salmon? or that mozzarella cheese made from cow's milk may have titanium dioxide added to adjust the colour to match that of traditional buffalo milk mozzarella?). Hmm, thought for food! Hope this helps Phil Philip Sheard Developmental Biology Unit, Department of Physiology, University of Otago Medical School, Dunedin, New Zealand.
